Flush or not to flush
Got a transmission service coming up for a DCT7 this week. Had the car for about 3 weeks, service was due at 70k but no documented evidence to suggest it’s had one, and millage is now 89k.
My question is, should I ask the garage to flush the transmission too before the new oil goes in?
I’m not sensing any slipping or delay or struggle in the changes.
Thanks!
Update: “no documented evidence”
